Motion in A Straight Line question

2024 · 29 Jan · Shift 2 · Q74

JEE MainPhysicsMotion in A Straight LineMCQ+4 / −1
A particle is moving in a straight line. The variation of position 'xxx' as a function of time 'ttt' is given as x=(t3−6t2+20t+15)mx=\left(t^3-6 t^2+20 t+15\right) mx=(t3−6t2+20t+15)m. The velocity of the body when its acceleration becomes zero is :
  1. A
    6 m/s
  2. B
    10 m/s
  3. C
    8 m/s
  4. D
    4 m/s
